Background
• December 2013, Explosive Accident
• Significant Review of Established Processes
• Training Criteria Became a Question
– How do we know our people are trained?
– OJT
° How do we know the quality is good?
° Is OJT consistent from one trainer to the next?
– How can we track it easily?
° EIMS can be a challenge
° Job Certification Training Record can be a challenge

Qualified Personnel
• High Voltage OP was coming due.
• Want to “…provide management and MOW
with confidence that qualified personnel are
safely conducting high voltage operations.”
• Multistep process to become qualified.
• Qualification levels include:
Reviewer
3
User
• Requirements
– Written Exam (20 questions), ELC 200, 3 year cycle,
Document high voltage equipment usage
• Purpose
– Users will have a fundamental understanding of high
voltage
– Prior to OJT with high voltage test equipment (hipotter and leakage tester) this qualification is
required
4
Builder
• Requirements
– User qualified + ELC 125 (3 year cycle)+ practical
exam (3 year cycle) + observe a high voltage system
build (one time) + build a high voltage system (1 year
cycle) + Maintain a copy of system review.
– Cannot power on the circuit the first time without
reviewer approval.
• Purpose
– Demonstrate capability to SME.
– Engage with reviewers.
– Understand electrical safety concepts.
5
Builder
• Practical Exam has the
candidate perform
fundamental tasks with
building high voltage
circuits
• Observe
– Shadow a qualified
Builder
6
Builder
• Build with oversight
from qualified builder
• Requires a schematic,
or block diagram, or
wiring diagram that can
be followed
• Cannot operate until
reviewed
• Schematic is archived
7
• Requirements
Designer
– User qualified + Builder qualified + design a high
voltage system to a design specification (1 year
cycle) + review + maintain a copy of design system
review + build (qualified builder) + review + maintain
copy of build review.
– A qualified design IS NOT required to be built
– A qualified build IS required to have a qualified
design
• Purpose
– Demonstrate capability to SME, engage with
reviewers, understand electrical safety concepts.

Reviewer
• Requirements
– User + Builder + Designer + BIT100 + OJT100 +
Observe a Build Review + Observe a Design Review
+ Perform a Build Review + Perform a Design
Review + ELC920 + Maintain copies of all reviews.
• Purpose
– Provide review and technical SME regarding high
voltage to Designers and Reviewers
9
Reviewer
• Instincts and experience
are critical to the
reviewer qualification
• The schematic template
prompts Reviewer to get
the required information
• Intended to get builder
and designers to engage
with an impartial SME
